Specification of Letters Patent.

Patented Dec. 14, 1920. This application lled September 18, 1919. Serial No. 324,327.

trolled valves for cutting off the flow when a predetermined amount of liquid has entered the same. One object of my invention is to provide a structure made wholly or substantially of non-metallic parts with a view of avoiding the deleterious effect which the waters of some localities and other liquids have upon metal structures and littings usually employed for this purpose.

A further object of my invention is to provide a structure simple in design and mode ot operation, and one that is readily attached to and detached from a tankand a further object of my invention is to provide'a structure of this general type that is less likely to be aected from the liquid with which it is employed than the metal structures heretofore in use.

To accomplish these ends, I propose to provide a structure in which all of the parts, or substantially all of them, shall be of nonmetallic material, and while there are, perhaps, many materialswhich might be employed for the purpose, I prefer to make the structure Yconstituting, my invention of some form of vitreous earthenware, such as china, or porcelain, or in some instances of glass.

In assembling a structure so made., it may in others to employ parts of other materials with the vitreous Vparts and, ofcourse, it may be desirable or necessary to emplo i structure to insure water-tight joints; all of i which is withinthe scope of my invention.

' These and other features of my invention are more fully described hereinafter, refer ence being had to the accompanying drawings, in which:

Figure l, is a view in elevationshowing f one form of valve structure within the scope .of my invention 'positioned with ,reference instances and desirable stem may be perforated at to the bottom of a flush or other tank with which it may be employed.

Fig. 2, is a sectional elevation of the same On the line II`II, Fig. 3.

j Fig. V3, is III-III, F ig. 2. Fig. his a plan view shown in Fig. 1.

Fig. 5, is a side elevation of a modified construction within the scope of my inven- 'of the structure tion, and liquid receiving tanks having loat-con Y Fig. 6, is a sectional elevation of the structure shown in Fig. 5.

In the accompanying drawings, l may .represent the bottom wall of a iiush tank with which my improved ball cock structure may be employed, and such tank may be of any ordinary construction and made of any suitable material. The body of my improved ball cock structure is shown at 2, and the lower part of the same may be provided with a dovetail projection 3 adapted to fit between the lundercut walls fl of a metal plate 5; such metal a sectional elevation on the line l threaded pipe section 6, to which the pipe i water (not shown) may be attached. If desired, the threaded pipe section 6 may be integral with the metal plate 5.

The dovetail projection 3 is' recessed on the underside as at 7, and adapted to this recess is a compressible gasket 8, with which the end of the pipe section 6 engages to insure a water-tight joint at this point. these parts are integral, vthe plate 5 will be provided with a seat for engagement with the gasket. The gasket S is apertured for the passage of liquid from the pipe section 6, and the bottom wall of the body of the ball cock structureis similari 10 in line therewith.

The body of the ball cock `structure is' j -same for engagement by a valve stem 13 vertically movable in said passage` and said rvalve stem is preferably provided with a L. gasket 14 at its lower end for engagement with the seat 12; such gasket being frictionally held in a recess in the end of said stem. Usually I provide a 'gasket suclras or contact with the seat, with a liller gasket 15 between the same and the bottom of the recess in the valve stem. The valve 16 so as tovfacil` usual ball float (not shown).

' as indicated in Fig. 3.

` the under side of the valve Y may be carried by tate dislodgment of the gasket 14 when it is necessary to replace the same. To avoid dislodgment of the filler gasket at the same time, it may also be perforated as indicated in the drawings. In lieu of this arrangement, the stem 13 1nay be cut away at 16 whereby access may be gained to remove the washer or washers when renewal is necessary, as shown in Fig. 6.

Irojecting above the body of the valve structure are ears 18, which may be apertured at 19 for the reception Vof a pinA 20, upon which is pivotally mounted a lever 21 for operating the valve stem 13, and such lever may carry the usual rod 22, to the opposite end of which may be attached'the To avoid displacement of the pivot pin 20, the body of the valve structure may be provided with an external pocket or recess 23 at one side of the same to receive a projecting arm 24: carried by said pin, and if desired, the end of the latter may be split, as clearly shown in Fig. 3. JAdditionally, the pocket or recess may have into which one of the prongs 24a of the split portion of the pin may be forced if desired,

In the present instance the lever for operating the valve stem is shown as having a yoked end 21il to embrace the stem 13, which is reduced at 13a, as clearly indicated in the drawings.

At one side of the valve body, I preferably provide a chamber 25, into which the inflowing water passes from the chamber 11 through an outlet port 26, and within this `chamber I preferably place a baille 27, which is preferably of metal connected to an after-lill pipe 28.. This baffle may be substantially Z-shape in cross-section, and one wall is Vpreferably perforated at 29 whereby the water may discharge into the the sound of the inflow being matethe use of perforations. 'Ihe lower end 27a of this baffle plate may be caught between the body of the 4ball cock structure and the plate 5.,

The structure shown in is designed to be secured to the tank through the medium of the dovetail projection on body. In some instances it may be desirable to secure the structure to the tank by other means, and

rially reduced by Figs. i, 2, e and a,

have illustrated by dotted lines projections securing screws which the valve body; these projections being illustrated in Figs. 1, 2 and 4.

In Figs. 5 and 6, I have shownr afvalve structureof this general type provided with projections 30 apertured at 31 for the reception of screws 32 whereby the body may be attached to the usual metal fitting 33 having a threaded stem 34, `passing through for the reception of 'plication in so far as the common sub an aperture 23L in its wall of said seats, lnection, and a gasket the wall of the tank and to which the water supply pipe (not shown) may be secured. Additionally, this form of ball cock structure may be provided with a yoke piece 36, usually of metal, through which one of the securing screws may pass and to which the operating lever 21a may be pivotally connected. The pin 20aL upon which this lever is hungmay have a pronged end 24h, as shownin Fig. 5, and such prongs may be bent to engage the wall of a pocket or recess 23b at the side of thebody structure, as shown in Fig. 5.

In all instances, the body and stem of the structure is made of vitreous material, clliina, porcelain, earthenware or the like, or g ass.v
